The good news, the bad news, John McCain was well McCain. He is not changing who he is.
Funny thing, McCain is seventy-two and his biography has no blank chapters. BO is but forty-seven, but his bio is full of blank chapters. McCain is far from perfect. He not pretend to be otherwise. BO is far from perfect but is running as if he were a messiah. McCain is selling an honest bill of goods.
Both BO and McCain are no messiahs, just men. McCain admits it.
